Embodiment

[0039]The main devices in the vehicle separation technology of municipal waste include: a rotating belt with a scraper, a roller-type press-cutting machine with spikes, a high-pressure mixer with an electric heating device, and a high-pressure heat extruder.

[0040] A method for separating and reusing municipal solid waste, the specific operation process of which is as follows:

[0041] 1) Transport the municipal waste to the treatment plant, dump it into the "eight"-shaped collecting tank 1, there is a scraping belt 15 at the bottom of the tank, and the scraping belt 15 has sharp toothed knives, and the garbage bag Scratched and forced to be sent to the crushing machine 3 equipped with the wolf tooth roller 2 to flatten, crush, and cut the garbage into fragments not larger than 10cm. A pool 14 is provided under the compacting machine 3, and the fragments fall into the water Enter detoxification and deodorization under the effect of strong mixer 13 (wherein cleaning agent and...

Abstract

The invention relates to a method for separating and regenerating the solid waste of city, belonging to the environment protection area. (1), incising the waste into fragments whose size is less than10cm to be mixed and washed in water and deposited in deposition pool for floatation; (2), feeding the waste into mixing device and feeding coal ash, low-melting point glass powder and chemical adjuster at following weight percents as waste fragment of 30-40%, coal ash of 35-45%, low-melting point glass powder of 20-30%, and chemical adjuster of 5-15% to be hot compressed molded; (3) feeding the heavy inorganic matter in the lowest layer of deposition pool into melting furnace to form the nepheline microcrystal glass; (4) feeding the food, greengrocery and paper powder of waste in the upper layer of heavy inorganic matter into firedamp pool; (5) the water of deposition pool can be supplied into the waster water treatment system of city. The advantages of said invention comprise: regeneration of waste, non-secondary pollution, unmanned selection, high automation degree, lower cost and high benefit.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to a method for separating and reusing urban solid waste (including urban factory waste and domestic waste). Background technique [0002] Urbanization is an inevitable trend of economic development. The most important problem in the service function of the city is the disposal of industrial waste and domestic waste generated every day. Similar mistakes have been made all over the world, such as collecting garbage in the suburbs for storage or storage. Burial, which not only wastes resources, but also pollutes the surrounding environment. In recent years, some countries have developed waste incineration technology, which not only wastes a lot of resources, but also aggravates "air pollution". There are some low-value utilizations of solid waste from factories. Such as: use power plant fly ash to make light-weight bricks, which are used for the walls of buildings. But harmf...
